Definitions
- Spectrally matched active illumination is also provided to identify and distinguish the tags from the background.
- Tags with a gonio-dependent spectral signature can be used to remotely reconstruct the profile of a surface or orientation of an entity.
- the invention can thus provide stand-off object characterization and tracking based on the associated tag or tags including the identity, location, orientation, speed, temperature, strain, deformation, humidity, elapsed time, gas and chemical substance concentration, shape and surface profile.
- FIG. 34 provides examples of the possible uses of structural-color tags as information carriers.
- (a) illustrates a spectral character coding scheme.
- the tags contain a website address pointing to additional information about the advertisement.
- the baggage labels contain structural-color tags associated with flight numbers allowing automatic tracking and verification of baggage.
- (d) an illustration of a possible deployment of the Invention in a warehouse or distribution center is provided.
- (e) exemplifies the remote identification and vetting of security personnel by worn tags.
- D ′ M ′ ⁇ ⁇ 2 ⁇ ⁇ cos ⁇ ⁇ ⁇ , ( Eq . ⁇ 2 )
- M or M′ is a positive integer, sometimes referred to as a fringe order or order of interference.
- spectroscopy such spectra are often referred to as frequency combs.
- the effects of phase shift due to reflection within the etalon are omitted (as in most textbooks) but can be accounted for by a material-specific scaling factor in M and M′, which is equivalent to using fractional M or M′ values.
- imaging embodiment ImE 6 enables a registration of tagged objects and their properties as identified by spectral camera sensor SCS onto the image output produced by visible camera sensor VCS.
- This capability can provide enriched video streams with associated object data, e.g., video frames with metadata on entities present within each frame as well as their properties and location.
